Description
Technical field
The present invention relates to printing device fields, and in particular to a kind of black-and-white printer goes out method for ink.
Background technique
For save the cost, existing black-and-white printer is mostly using Split type ink box.In actual application,
Split type ink box is typically directly directly connected to the nozzle of printer, is allowed the ink in print cartridge to enter directly into and is completed to beat in nozzle
Print.
Specifically in order to protect printer head, it will usually be arranged in print cartridge the obturators of porous medias such as sponge or
Other regulators, to guarantee to allow the ink in print cartridge at the uniform velocity can enter spray head in a pressure constant state in print cartridge
In.But by the way of obturator, the space in print cartridge can be occupied, leads to the volume decline of the ink contained in print cartridge, because
This present print cartridge carries out using regulator pressure controlled in print cartridge mostly.
But it is specifically used during, the print cartridge of printer is in a static state, it is known that ink
Precipitating can be generated after standing a period of time, these precipitatings for printer head be it is fatal, in order to avoid this problem,
Producer is mostly the feeling that many regions or even somewhat similar labyrinth are separated out in the print cartridge of printer by the way of, is allowed
Multithread is dynamic as far as possible in labyrinth for ink, this is really a mixed uniformly process, is the stability in order to improve printing.Such as love
The printer of general life is usually exactly above structure.
In actual use, it prevents to precipitate by above-mentioned method for ink out, still there is undercompounding, be easy
The technical issues of generating precipitating.
Summary of the invention
The present invention goes out method for ink there are undercompounding for existing black-and-white printer, and ink is easy to produce the skill of precipitating
Art problem provides a kind of black-and-white printer and goes out method for ink.
Base case provided by the invention are as follows: black-and-white printer goes out method for ink, realizes by following device:
Black-and-white printer, including body, controller, spray head and it is mounted on the intracorporal print cartridge of machine；Print cartridge includes: box body, adjusts
Pressure system, stirring system and reflux line；
Setting venthole and air inlet above box body are provided with ink hole below box body, be equipped at ink hole for spray
The ink tube of head connection, is additionally provided with for controlling the solenoid valve that whether ink flows out in box body at ink hole, is additionally provided in box body

After signal, then control pressurization pump startup controls control booster pump while solenoid valve is opened and closes, controller is also used to connecing
It receives printer to complete after printing, control solenoid valve is closed, then control pressurization pump startup, and finally control booster pump stops；
Include the following steps:
S1: starting booster pump, reflux line is interior to form negative pressure, and residual ink in ink tube is caused to flow；
S2: pressure limiting valve is opened, and air can enter in booster pump from pressure limiting valve, and then air after booster pump by entering
In pressure inlet, enter finally into air inlet pipe；
S3: air is entered in box body in the form of bubble from the lower end of air inlet pipe, and impeller is rotated using the buoyancy of bubble
Get up, then drive stirring net vibration, so that the intracorporal ink of box is stirred mixing, the intracorporal pressure of box increases, lets out reaching
After the triggering pressure of pressure valve, relief valve is opened, and air is discharged from the relief valve of venthole；
S4: the solenoid valve at ink hole is opened, and ink enters ink tube from ink hole, enters finally into spray head.
The working principle of the invention and advantage are: when printer needs to print, booster pump starts first, and booster pump opens
The air pressure that will lead in reflux line after dynamic reduces, and then causes the air pressure in ink tube to reduce, will cause the remaining ink in part
The flowing of water, is even inhaled into reflux line.With the further work of booster pump, negative pressure is formed in reflux line
Afterwards, pressure limiting valve can be opened, and air can enter in booster pump from pressure limiting valve, and then air is by entering pressure inlet after booster pump
In, it enters finally into air inlet pipe.
Box body is provided with ink at this time, and air enters from the upper end of air inlet pipe, and the lower end of air inlet pipe is located under box body
Portion, air can be entered in box body in the form of bubble from the lower end of air inlet pipe at this time, and bubble can be from the lower end of air inlet pipe
It rises, the intracorporal pressure of box is then allowed to increase, after reaching the triggering pressure of relief valve, relief valve is opened, and air is from venthole
Relief valve discharge.Then it controls the solenoid valve at ink hole to open, ink enters ink tube from ink hole, enters finally into spray
In head, print job is completed.
Bubble is generated in box body can achieve the purpose that stir ink in box body, and then bubble rose box is intracorporal
Cheng Zhong, can allow wheel rotation, i.e. impeller is rotated using the buoyancy of bubble, stirring net vibration then be driven, so that in box body
Ink be further stirred.
Black-and-white printer of the present invention goes out method for ink, by before printing, allowing booster pump to form negative pressure in ink tube, in this way
Operation can promote printing effect to avoid bubble is generated in pipeline out of ink, and be also possible that ink is initially entering
There is stronger mobility after in pipeline out of ink, enhance stirring capacity, precipitating is avoided to generate；On the other hand gas is allowed to enter
Into box body, gas can allow the mobility of enhancing ink, and can drive stirring net, further increase ink in box body
Mobility reaches well-mixed purpose.
Further, in S4, filter tip is additionally provided in ink tube, filter tip is mandruka structure, and ink is laggard by filter tip
Enter into ink tube.
It is such design be in order to generate precipitating in the ink after, filter tip can also filter out partial impurities, play guarantor
Protect the purpose of nozzle.
Further, it in S3, stirs and is equipped with elastic component between net and the bottom of box body, allow stirring net multiple back and forth
Vibration.
Such design is the mixing effect of enhancing stirring net in order to allow elastic component driving stirring net to vibrate back and forth.
Further, in S3, sponge is provided at venthole, when gas is discharged from the relief valve at venthole, absorption
The foam that ink generates.
Such design is that the foam generated in ink after entering ink in order to avoid air is overflowed from venthole.
It further, further include S5, setting has a margin detection sensor in air inlet pipe, is detected sense by surplus after printing
Ink surplus of the device into user feedback print cartridge.
Such design is that remaining quantity of ink in print cartridge is got in order to facilitate user.
Further, in S3, stirring is fixedly provided with supporting plate on the net, and supporting plate follows stirring net movement.
Stirring and mixing effect can be enhanced in such design.
